GAR-DOOR ROLLER.

Application filed December 18, 1922. Serial No. 607,573.

To all 21 7mm it may concern:

Be it known that we, Crrannns MoGoWAN,

, GUsTAr Pn'rnnsoN, and ARTHUR A. LUND,

citizens of the United States, residing at 'Susanville, in the county of Lassen and State of California, have invented certain new and useful Improvements in Car-Door Rollers, of which the following is a specification.

Our invention relates to an improvement in car door rollers specifically adapted for attachment to car doors, whereby the loading of the car is expedited and further, wherein the present roller is so devised as to fit any type of car door and to be substantially adjustable thereon, or rather, be-

tween the car door and the door post.

The primary object of the invention resides in the provision of such a device that is comparatively simple of construction,

easy of installation and highly efiicient of operation.

The nature and advantages of the inven tion will be betterunderstood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application. like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in front elevation of a device constructed in accordance with the present invention, the same being shown in position upon a car,

Figure 2 is a longitudinal cross sectional view upon the line 2--2 of Figural.

Figure 3 is a view similar to Figure 2, but taken upon the line 3-3 of Figure 1.

Figure 1 is a fragmentary top plan. view of the device. partly in'cross section, the roller beingshown in full and dotted line positions, and

Figures 5 and 6 are sectional view taken on the lines 5-5 and 66, respectively, of Figure 1, looking in the direction of the arrows.

In the drawings, we have shown our device applied to a convenient type of freight car A, provided with the usual sliding door B thereon. The roller includes a relatively elongated angle bar 5, preferably U-shape in cross section, and being longitudinally slotted adjacent its outer ends as at 6, further, the bar is also longitudinally slotted at its central portion as at 7.

Slidably disposed in each end slot 6 is a bolt 8, having a headed or hooked inner end 9 and being screw threaded for a portion of its length as at 10. Pivotally secured to the upper end of each bolt 8, is the yoked end 11 of a swinging arm 12, which arm has formed on its outer end a hook or head 13, extending in an opposite direction to the hook or head 9 of its complementary bolt 8. Each of the legs constituting the yoked ends of the arms 12 are hooked as at 14 for engagement with a cross pin 15 carried by the bolts 8 for limiting the backward swinging movement of the arms 12. Nuts 16 with integral handle members 17 are adapted for screw threaded arrangement upon each bolt 8, and the inner face of each nut 16 has a washer 18 formed thereon, for wedging engagement with the adjacent face of the bar 5 in a manner hereinafter described.

In view of the above description, it-will be readily understood that the bar 5 may be conveniently adjustably supported between one vertical edge of the car door B, and the adjacent vertical edge of the door opening or post in the car A. As shown in Figure 2, one of the endbolts 8 is turned within its complementary slot 6, and is so disposed therein, as to allow the headed or hooked end 13 of the swinging arm 12 to engage over the edge of the car door opening or door post, where it may be rigidly secured by the nut 16. The other bolt 8 at the opposite end of the bar 5, has its hooked end 9 engaging over the edge of the door B. The arm 12 in this instance, being swung inwardly as shown in Figure 3. This bolt 9 is also rigidly secured between the door and bar 5 by the securing nut 16 thereon.

As before mentioned, the bar 5 is of U shape. and slidably disposed between the top and bottom flanges formingv this bar. is a metallic block 19 projecting'outwardly of the flanges of the U bar 5, as more clearly shown in Figures 5 and 6 and longitudinally shouldered at 20 upon its upper and lower edges for close contact with the ends of the flanges of the U bar,

Extending vertically through the projecting portion of the block 19, and slightly on center, as'show'n, is a bolt 21, headed at its upper end as at 22, and screw threaded at its lower end as at 23. Between the headed end of the. bolt, and the upper surface of the block 19 and adjacent flange of the bar 5, isa relatively en'longated U-shaped roller carrying bracket 23, which has an opening 24 therein, for receiving the said bolt 21.

This roller carrying bracket 23 has secured thereto an arm or plate 25, which engages over the head 22 of the bolt 21 as more clearly shown in Figures 1 and 5, for preventing rotation of this bolt within the block 19. The vertical end legs comprising this roller carrying bracket are each provided with a screw threaded opening 26 therein, for receiving set screws 27, the inner ends of which are pointed as at 28, and these set screws are adjustable within the openings of the bracket legs by nuts 29. The pointed ends 28 of these set screws 27 are adapted for engagement within the coupled ends of what may be termed an annular shaft 30.

Engaging overth's shaft'is a fiber roller 31,

which is preferably crowned or convex as shown in Figure 4. The opposite ends of the shaft 30 are screw threaded, and the roller 81 is maintained thereon by nuts 32 engaging over the screw threaded ends of the shaft and having openings33 in the periphery thereof for receiving the lugs of a spannerwrench or the like whereby these nuts may be separated.

The lower screw threaded end of the bolt 21 isadapted to receive a nut 34 having a handle35 formed thereon, and it will be readily understood that when this nut is screwed away from the block 19 and lower flange of the U-bar 5, the roller bracket 23 may be adjusted to any angle desired, to-be secured in its adjusted positionby screwing the nut 34 upon the bolt 21.

1 The block 19 has another bolt 36 extending therethrough and at right angles to the i bolt'21. Thisbolt is headed'at 37 at one end and screwthreaded'at '38- at its opposite end. This screw threaded bolt is adapted for projection through the central slot 7 in the bar 5. Adapted for screw threaded engagement upon the screw threaded end of this bolt is a nut 39 adapted to be screwed up on the bolt when the r0l-ler'31 has been properly adjusted on the bar. 5.

In view of the abovedescription, it will be readily seen that the bar 5 may be adjusted and secured in its adjusted pos tion at any desired point between one edge of the car door post, andfurther, tliat'each'of the bolts 8 and the arms 12 may be so adjusted in the slots6 of the bar as to have either the head 9 of the bolt or the head 13 of its associate arm engage with either the edge of the car door or the car door post. Further,

:these bolts may be longitudinally adjusted with respect to the bar 5 for obvious purposes, and again the roller 31 may be adjusted at any angle desirable with respect to' the opening in the car body.

\Vl1ile it isbelieved that from the fore-' going description, the nature and advantages of the invention will be readily apparent, We desire to have it understoodthat we do not limit ourselves'to what is herein shown and described, and that such changes may be resorted to when desired as tall withinthe scope of what is claimed.

What we claim as new is: 1. A device of the class described comprising a. supporting bar of channel form having longitudinally extending elongated slots in the web thereof and at its. ends, bolts extending through and slidably disposed in said slots and having nuts threaded upon the outer ends thereof, said bolts being pro-- vided with laterally extending inner ends" bolt tor: adjustably clamping the block.

against sliding movement, anda' roller supporting bracket pivotally mounted on said block. y A I 2. A device of the class described comprising a supporting bar of channel form hav ing longitudinally elongated slot-sin the web thereof and adjacent the ends of the S8.l1'l,-b0ltS extendingthroughsaid slots and having laterally projecting inner ends facing in one direction to provide clamping arms, arms pivoted to the inner ends of the bolts andhaving hooked free ends extend ing laterally in a direction opposite to that,

in which said clam-ping arms'project, ends upon the outer ends of said bolts for elamp 'ing the same adjusta-bly in said slots. and "a roller carrying bracket adj ust-able longitudinally on the supporting bar intermediate its ends. a

In testimony whereof weatiix our-signatures.
